Question bash: ns: command not found using ns-2.31


Hey,

After installing ns-2.34, evtg worked fine, however I wanted to install the crcn (cognitive radio) add-on I had a lot of prablem in the Makefile.in. However the crcn is tested till ns-2.31. I installed ns-2.31 but after installation I cannot use ns. It doesn't enter to the program. It gives me this msg:

The program 'ns' is currently not installed. You can install it by typing:
apt-get install host
bash: ns: command not found

however doing apt-get install host is not the solution, it install another kind of command.

I don't also think the problem is from the path because I added this and still not working:

NS=/home/victor/Desktop/NS2-2.31/ns-allinone-2.31/ns-2.31/
NAM=/home/victor/Desktop/NS2-2.31/ns-allinone-2.31/nam-1.13/
export PATH=$PATH:$NS:$NAM


Maybe I got the PATH wrong or smtg. What to do ? Any ideas?

Thank you!

You could be absolutely sure the program is installed if you run it with the full path, such as:

/home/victor/Desktop/NS2-2.31/ns-allinone-2.31/ns-2.31/ns

I'm guessing the path - I have never used this program specifically.

To find the correct path, you should "find" it. Supposing the file is in the $NS directory, do:

find $NS -name "ns"

And this should return the specific location of the ns file, if it is inside the $NS directory. Try running it, and if there is an error, please post it here.

Hey,

The ns worked, I dunno exactly how it worked, but when I run the gnome-terminal it worked. and when I enter the directory, and run ./ns it also go to %.

Anyway I have a new problem, I think due to nam 1.13. The error given:

nam:
[code omitted because of length]
: no event type or button # or keysym
while executing
"bind Listbox <MouseWheel> {
%W yview scroll [expr {- (%D / 120) * 4}] units
}"
invoked from within
"if {[tk windowingsystem] eq "classic" || [tk windowingsystem] eq "aqua"} {
bind Listbox <MouseWheel> {
%W yview scroll [expr {- (%D)}] units
}
bind Li..."

What to do? Any ideas?

Thank you

I found this thread for Fedora, see if applying the patches solves your problem:

Problem with Makefile

Hi,

I am new user of ns2 and want to simulate the Cognitive Radio MAC protocols like SYN-MAC and C-MAC.

Therefore, I decided to try the CRCN patch.

But on the step5 of stuweb.ee.mtu.edu/~ljialian/installation.htm , they have not mentioned about pasting the given lines on which lines of Makefile
of ns2 folder.

So, If I'd paste it on whichever location, I got error message while doing 'make clean' and 'make'.
After this, my ns command also stops working.

Could you please help me with this problem please.

Problem on Makefile for crcn patch in ns2

Hi,

Thanks for the response.

I am using Ubuntu 10.04 OS.

ns version is : ns 2.34.

I have installed the ns2 (all in one) in my home directory.

Hope this could help to identify and resolve my problem.

Thank you and looking forward to hear from you.

The crcn patch is for ns-2.31 > > ns-allinone-2.31.
It didn't work in ns-2.34.

The four (not three) new Makefile lines :
I added them to Makefile.in instead.
Some editing is required : Each line has 8 spaces : Not allowed.
Replaced by one <TAB>. Location : Line 311-312-313-314.
Please rename Makefile (if present) to Makefile.old, then :
1) export CC=gcc-4.1 CXX=g++-4.1
2) ./configure && make clean && make depend && make
... and you have a "CRCN ns".

The attached Makefile.in.txt : Rename to Makefile.in
..

File Type: txt Makefile.in.txt (18.0 KB, 145 views)

Hi,

Thank you for your reply.

I removed ns allinone 2.34 and extracted 2.31 in my home directory (/home/sunil/).
Then I extracted the files of crcn.zip into ns-2.31 folder (with overwriting existing files).
I renamed makefile and Makefile.in in ns-2.31 folder to makefile.old and Makefile.in.old respectively
Then I saved the Makefile.in.txt provided by you on the ns-2.31 folder as Makefile.in .
After this, I did export CC = gcc-4.3 (My gcc verson, hope this doesn't matter)

Then I ran ./install which completed.

After this, I tried to run CRCN.jar which worked for some and did not for others. However, I don't find CRCN.jar handy.

Is this method correct? I am not sure because I cannot device a code to validate it.

Could you please provide me any simple sample code for Cognitive Radio MAC protocol if you have any. (or perhaps any web link where I could learn)

Anyway, I am very very much thankful for your support.

Thank you again,
Sunil

How to install NS2 with Ubuntu 10.04 By Noor Zaman

This manual will work for NS2 allinone-2.34 with Ubuntu 10.4. As Ubuntus new version 10.04 needs following packages before any further installation, otherwise it will not work with it.
Please follow the following steps:

1. Install necessary tools for building:

sudo apt-get install build-essential autoconf automake libxmu-dev gcc-4.3

2. It turns out that otcl does not like the version of gcc installed by default in Lucid. So go ahead and change ns-allinone-2.34/otcl-1.13/Makefile.in. Find the line that says:

CC= @CC@
and change it to:
CC= gcc-4.3
3. Now follow the following steps for installation of nsallinone 2.34 and it will work with your machine. (copy ns-allinone-2.34.tar.gz)

Suppose that there is "ns-allinone-2.33.tar.gz" in current directory (e.g. "~/" for me is "/home/noor").
All steps are done in Terminal, so open a terminal in Accessories/Terminal.To extract the file:
tar xvfz ./ns-allinone-2.33.tar.gz


4. Change your directory within terminal as following way

$ cd /home/noor$ cd /home/noor/ns-allinone-2.34

5. Download & install some packages from repository if needed (Now its optional)

$ sudo apt-get install build-essential autoconf automake libxmu-dev
6. Install the ns2

$ cd ns-allinone-2.34
$ ./install
7. Edit some paths

$ gedit ~/.bashrc
8. Put these lines on that file in the last. Off course, you might change /home/noor for it depends on where you extract ns-allinone-2.34.tar.

# LD_LIBRARY_PATHOTCL_LIB=/home/noor/ns-allinone-2.34/otcl-1.13NS2_LIB=/home/noor/ns-allinone-2.34/libX11_LIB=/usr/X11R6/libUSR_LOCAL_LIB=/usr/local/libexport LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB# TCL_LIBRARYTCL_LIB=/home/noor/ns-allinone-2.34/tcl8.4.18/libraryUSR_LIB=/usr/libexport TCL_LIBRARY=$TCL_LIB:$USR_LIB# PATHXGRAPH=/home/noor/ns-allinone-2.34/bin:/home/noor/ns-allinone-2.34/tcl8.4.18/unix:/home/noor/ns-allinone-2.34/tk8.4.18/unix:/home/noor/ns-allinone-2.34/xgraph-12.1/NS=/home/noor/ns-allinone-2.34/ns-2.34/NAM=/home/noor/ns-allinone-2.34/nam-1.13/export PATH=$PATH:$XGRAPH:$NS:$NAM

9. Validate it (take very long time compare to install process)
$ cd ns-2.33$ ./validate

10. Let it take effect immediately

$ source ~/.bashrc

11. Try to run it as following way, by just typing ns with terminal

$ ns
12. If the installation is successful, then you will be able to see % at the command prompt. Type following command to exit
% exit

13. Good luck and please keep remember me in your prays(Thanks in advance). Noor Zaman, King Faisal University, Saudi Arabia.


sir pls help me...thanks in advance.....

#12, @Gunasekaran : sudo apt-get install g++-4.1

Installing ns-allinone-2.31 :
cd ns-allinone-2.31/ && export CC=gcc-4.1 CXX=g++-4.1 && ./install

Quote:
7. Edit some paths
$ gedit ~/.bashrc
.
.
10.
$ source ~/.bashrc
Not required.
And will make 'ns' functions impossible when you have more than one version of ns-allinone-2.xx.
'ns' and 'nam' are hard coded to know where their libraries are located.
And : 'cd ns-allinone-2.31/ns-2.31/ && sudo make install' copies ns to /usr/local/bin/ .
The same for 'nam'. Then both binaries are in a "system PATH".

Hello,
I am running ns-allinone-2.35 (downloaded from sourceforgenet) on ubuntu 10.10. My ns is working properly. However when i try to run nam, its showing the following error:

$ nam
nam: Can't find a usable tk.tcl in the following directories:

invoked from within
"source $HOME/ns-allinone-2.35/lib/tk8.5/tk.tcl"

This probably means that tk wasn't installed properly.


However, when I double click on the executable inside $HOME/ns-allinone-2.35/bin the nam is opening.
What could be the problem.
PS: I have set all the environment variable as directed after the ./install
Thank you.
